2 Claims, N0 Drawings CLEANING COMPOSITION FOR INKS, PENCILS AND VARIOUS SOILS BACKGROUND OF THE INVENTION This invention broadly relates to a new cleaning composition.

There has long been a problem in the art of removing various stains and markings left on clothes, walls, and the like from ink pens, pencils, etc. For example, writing instruments left in a pocket or accidentally moved across the surface of a persons clothes frequently leave undesirable marks which are extremely difficult to remove. Moreover, washroom walls and the like are frequently written on with various writing instruments such as ink pens, felt-tip pens, pencils, and the like to detrimentally affect the appearance of the walls. Accordingly, a primary object of this invention is to'provide a unique new cleaning composition capable of removing markings left by inks, pencils, felt-tip pens, etc., without damaging the substrate on which the markings exist.

Accordingly a primary object of this invention is to provide a cleaning composition which is capable of removing such markings in an easy manner not hereto- In still another aspect the present invention concerns a cleaning composition suitable for removing markings left by inks, pencils, and the like, comprising: a carrier base material of ethoxylated fatty acid, and at least one 5 material selected from the group consisting of, an alkylated acid amide, a alkyl acid ester, monoglyme, diglyme or triglyme.

Broadly stated, the present invention also concerns a cleaning composition suitable for removing markings left by inks, pencils, various soils and the like, comprising: (a) a carrier base material of C -C liquid surfactant, such as the above specified tall oil fatty acid, (b)

a solvent material selected from at least one material of the group consisting of an alkylated acid amide, a alkyl acid ester, monoglyme, diglyme or triglyme.

DESCRIPTION OF PREFERRED EMBODIMENTS In order to specifically illustrate the invention the following example material is provided. It is to be understood however that the examples a're included for illustrative purposes and are not intended to be limiting of the scope of the invention as set forth in the subjoined claims.

TABLE OF EXAMPLES (amounts in milliliters) Component ethoxylated tall oil Example: 1 2 3 4 5 110 lOO fatty acid dimethyl formamide tertiary butyl acetate monoglyme diglymc triglyme SUMMARY OF THE INVENTION It is not fully understood why the inventive discovery made and disclosed herein works in such a uniquely satisfactory manner to remove ink and pencil markings and the like from almost any kind of substrate. However, suffice it to say that the cleaning composition discovered has given extremely satisfactory results and also the cleaning composition discovered is economical and practical to produce.

In one preferred aspect, the present invention concerns a cleaning composition suitable for removing markings left by inks, pencils, and the like, comprising in parts by volume: 100 parts of a carrier base material of ethoxylated tall oil fatty acid of the general formulation RCOO(CH CI-I O)xlCH CI-I OH, 20 parts of dimethyl formamide, 20 parts of tertiary butyl acetate.

In another aspect, the present invention concerns a cleaning composition suitable for removing markings left by inks, pencils, and the like, comprising: a carrier base material of ethoxylated fatty acid, an alkylated acid amide, :1 alkyl acid ester.

lIu-wS YJIUIC mlll;

The cleaning composition discovered and disclosed herein has been found to uniquely and satisfactorily remove inks, pencil marks, greases, and other soils from a variety of surfaces as well as fabrics, or from the skin, without any observable detrimental effect. Accordingly, the advantages to be derived from this invention should be fairly apparent. For example, a good workable cleaning composition which functions to remove markings left by inks, felt-tip pens, and pencils has heretofore been either unknown in the art or prohibitively expensive and therefore it is believed that the invention disclosed herein is of relatively broad commercial application.

While it will be apparent that the preferred embodiments of the invention disclosed are well calculated to fulfill the objects above stated, it will be appreciated that the invention is susceptible to modification, variation, and change without departing from the proper scope or fair meaning of the subjoined claims.

What is claimed is: l. A cleaning composition suitable for removing markings left by inks, pencils, and the like,

consisting essentially of in parts by volume:

parts of a carrier base material of ethoxylated tall oil fatty acid,

20 parts of dimethyl formamide, 20 parts of tertiary butyl acetate.

2. The composition of claim 1 wherein.

there is also included an effective amount, to perform said cleaning of a glycol dimethyl ether material selected from at least one of the group consisting of munoglycol dimcthyl other. diglycol dimethyl ethr or triglycol dimethyl ether. 

1. A CLEANING COMPOSITION SUITABLE FOR REMOVING MARKINGS LEFT BY INKS, PENCILS, AND THE LIKE, CONSISTING ESSENTIALLY OF IN PARTS BY VOLUME: 100 PARTS OF A CARRIER BASE MATERIAL OF ETHOXYLATED TALL OIL FATTY ACIDS, 20 PARTS OF DIMETHYL FORMAMIDE, 20 PARTS OF TERTIARY BUTYL ACETATE.
 2. The composition of claim 1 wherein, there is also included an effective amount, to perform said cleaning of a glycol dimethyl ether material selected from at least one of the group consisting of monoglycol dimethyl ether, diglycol dimethyl ether or triglycol dimethyl ether.
